Product details
Overview
HZK3CLLTR-S-E from Renesas Electronics is a silicon planar Zener diode optimized for hard-knee, low-noise voltage reference applications at low currents. It delivers a nominal Zener voltage of 3.3 V (min 3.1 V, max 3.5 V), dynamic impedance of 360 Ω at IZT = 0.5 mA, and reverse current ≤100 nA at VR = 1.0 V. Its LLD surface-mount package supports high-density PCB layouts in precision analog power rails and sensor biasing circuits.
For engineers reviewing the HZK3CLLTR-S-E datasheet, HZK3CLLTR-S-E pinout, HZK3CLLTR-S-E application, or HZK3CLLTR-S-E equivalent, key selection criteria include its low-noise hard-knee Zener behavior, tight 3.1–3.5 V tolerance at 0.5 mA, 250 mW power rating, −55 to +175 °C storage range, and suitability for stable low-current references in industrial and communications equipment.
Technical Context
The HZK3CLLTR-S-E employs a silicon planar junction structure engineered for minimal dynamic impedance (360 Ω typ.) and low noise in the 0.001–0.5 mA operating region - approximately one-tenth that of conventional Zeners. Its hard-knee characteristic ensures sharp turn-on with minimal voltage hysteresis below 1 mA.
Designed for DC-stable reference use, it exhibits a Zener voltage temperature coefficient of ≈−2.0 mV/°C near 3.3 V (per Fig.2), and operates within a junction temperature limit of 175 °C. The device is rated for 250 mW dissipation on standard PCB mounting per JEITA spec GLZZ0002ZA-A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.1–3.5 V at IZ = 0.5 mA - defines precise low-current reference point for analog circuitry |
| Dynamic Impedance (ZZT) | 360 Ω typ. at IZT = 0.5 mA - enables stable regulation under small-signal load variations |
| Reverse Current (IR) | ≤100 nA at VR = 1.0 V - ensures negligible leakage in high-impedance bias networks |
| Power Dissipation (Pd) | 250 mW on PCB - sets maximum continuous DC power handling without derating |
| Junction Temperature (Tj) | 175 °C max - allows operation in thermally demanding industrial environments |
| Storage Temperature | −55 to +175 °C - supports wide-range logistics and long-term reliability in harsh conditions |
Pinout & Package
The HZK3CLLTR-S-E is housed in the LLD (Leadless Low-profile Diode) package - a 2-pin, surface-mount, glass-epoxy compatible case measuring 2.5 × 3.0 mm with 1.25–1.45 mm height and typical mass of 0.027 g. JEITA code GLZZ0002ZA-A; Renesas package code LLD.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to higher-potential node; Zener breakdown occurs when cathode-to-anode voltage exceeds VZ |
| 2 | Anode | Connected to lower-potential node (typically ground or return); completes reverse-bias path for reference operation |
Key Features
| Feature | Design Value |
|---|---|
| Hard-knee Zener characteristic | Sharp, low-hysteresis turn-on at ~3.3 V with ΔVZ1 ≤ 0.5 V and ΔVZ2 ≤ 0.6 V across 1 µA–0.5 mA range |
| Low-noise performance | Approximately 1/10 the noise of standard Zeners in low-current region - critical for precision sensor excitation |
| LLD surface-mount package | Compact 2.5 × 3.0 mm footprint enabling high-density layout and compatibility with automated SMT assembly |
| Stable low-current regulation | Specified down to IZK = 0.5 µA - supports micropower reference designs without external amplification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C3V3 (Nexperia) | 3.3 V ±5%, 300 mW, 600 Ω ZZT at 5 mA - higher impedance, higher test current, wider tolerance | Targeted at general-purpose regulation, not low-noise or hard-knee operation | Acceptable where cost sensitivity outweighs noise and knee-sharpness requirements |
| MMSZ4685 (ON Semiconductor) | 3.3 V ±5%, 500 mW, 30 Ω ZZT at 20 mA - lower impedance but only specified at high current; no low-IZ data | Optimized for higher-current shunt regulation; lacks verified sub-1 mA noise or knee performance | Preferred for higher-power reference buffering, not micropower or low-noise signal chains |
Compared with BZX84-C3V3 and MMSZ4685, the HZK3CLLTR-S-E uniquely combines hard-knee behavior, 100 nA leakage at 1 V, and 360 Ω impedance at 0.5 mA - making it the only option among the three validated for precision low-current reference design in industrial and portable instrumentation.

FAQ
What is the Zener voltage tolerance of the HZK3CLLTR-S-E?
The HZK3CLLTR-S-E has a guaranteed Zener voltage range of 3.1 V to 3.5 V when tested at IZ = 0.5 mA, corresponding to a nominal 3.3 V rating with ±0.2 V absolute tolerance. This tight spread supports accurate voltage referencing without post-manufacturing trimming in industrial and instrumentation applications where the HZK3CLLTR-S-E is deployed.
Does the HZK3CLLTR-S-E support low-current operation below 1 mA?
Yes, the HZK3CLLTR-S-E is explicitly characterized down to IZK = 0.5 µA and exhibits hard-knee behavior across 1 µA–0.5 mA. Its dynamic resistance remains stable at 360 Ω (typ.) even at IZT = 0.5 mA, confirming reliable low-current regulation - a core design objective of the HZK-LL Series reflected in the HZK3CLLTR-S-E's specification table.
What is the thermal performance limit of the HZK3CLLTR-S-E?
The HZK3CLLTR-S-E has a maximum junction temperature (Tj) of 175 °C and a storage temperature range of −55 to +175 °C. Its 250 mW power dissipation rating applies to standard PCB mounting (per JEITA GLZZ0002ZA-A), and thermal derating begins above 25 °C ambient per the published Pd vs. Ta curve in the HZK-LL Series datasheet.
Is the HZK3CLLTR-S-E RoHS compliant and lead-free?
Yes, the HZK3CLLTR-S-E meets EU RoHS Directive requirements and is manufactured as a lead-free device. Renesas confirms environmental compliance per applicable regulations, and the LLD package uses lead-free terminations - consistent with Renesas' corporate policy stated in the document footer and reinforced by RoHS markings on official distribution channels.
How does the noise performance of the HZK3CLLTR-S-E compare to standard Zener diodes?
The HZK3CLLTR-S-E delivers approximately one-tenth the noise of conventional Zener diodes in the low-current region (0.001–0.5 mA), as stated in the "Features" section of the official Renesas datasheet REJ03G0020-0300. This low-noise trait is intrinsic to its silicon planar structure and hard-knee design, directly benefiting HZK3CLLTR-S-E applications in precision sensor excitation and high-resolution ADC biasing.
